BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an improved structure of a winding reel, and particularly to a winding reel adapted to assemble, convey and store up easily.

2. Description of the Prior Art

Extension-core sockets have become very popular in daily life since they can timely solve the lack of sockets for power supply in common houses or working sites, especially when there is no socket available for indoor electronic appliances, bulbs hung on the tree, or workers in the outdoors. Therefore, the extension-cord sockets are very widely used. The convenience of the extension-cord sockets comes from the length of the power supply line is so long that the electric power can be introduce to anywhere in the outdoors. Although the longer power supply line provides significant convenience to use the electricity, it also causes the problems in collection and storage.

In order to collect the power supply line easily, winding reels are proposed. Conventional winding reels are formed into a I-shaped reel, so that the power supply line can be wound on the reel. However, the conventional winding reels are not detachable and their volumes are large, it is not easy to move, store, manage and convey these winding reels.

Therefore, in view of the above, the conventional winding reels still have some drawbacks, and really need to be improved.

In view of the above problems in conventional winding reels, the inventor of the present invention thus employs his expert experiences in this field to propose an improved structure of the winding reel.

SUMMARY OF THE INVENTION

The present invention is to provide an improved structure of the winding reel, wherein the winding reel can be divided into a first reel cover, a second reel cover and a rotating ring to reduce the total volume of the winding reel in conveying. When the winding reel is to be used, the user just needs to assemble it by himself.

Another, the present invention is to provide an improved structure of the winding reel, wherein a rotating ring having a handle is pivotably connected to the joint between the first reel cover and the second reel cover, such that the user can hold the handle of the rotating ring to wind the power supply line.

Accrodingly, the winding reel of the present invention comprises first and second reel covers each having a through hole in the center and a rotating ring, wherein a hollow positioning shaft is extended in the center of the first reel cover. The hollow positioning shaft is circumferentially provided with a flange adjacent to the wall face of the front end. The flange is provided with at least one fastening notch. An inner ring body and an outer ring body are extended in the center of the second reel cover. A pivoting notch is formed between the inner and outer ring bodies. At least an elastic fastener is extended from an upper end of the outer ring body. At least one elastic fastener is provided on the bottom end of the inner ring body. The positioning shaft of the first reel cover is connected to the outer ring body of the second reel cover such that the elastic fastener provided in the outer ring body of the second reel cover is fastened into the fastening notch provided on the flange of the first reel cover, and thus the first reel cover and the second reel cover can be firmly connected to each other without being easily separated. A handle is provided in the rotating ring. The rear end edge of the rotating ring is circumferentially provided with a stopping portion extending outwardly. The front end of the rotating ring is circumferentially provided with a fastening portion extending inwardly. The front end of the rotating ring is positioned into the pivoting notch of the second reel cover via the first reel cover, such that the fastening portion of the front end of the rotating ring can be fastened to the elastic fastener provided on the bottom end of the inner ring body of the second reel cover. The stopping portion on the rear end abuts against the flange of the first reel cover, such that the rotating ring cannot pass through the pivoting notch. As a result, the user can simply hold the handle of the rotating ring to twirl the first reel cover and the second reel cover, and thus achieve the winding of the power supply line.

These features and advantages of the present invention will be fully understood and appreciated from the following detailed description of the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to FIGS. 1 to 3, the winding reel of the present invention mainly comprises the following members.

A first reel cover 1 is provided. A through hole 11 is provided in the center of the first reel cover 1. A plurality of openings 12 are circumferentially provided on the first reel cover. Each opening 12 is provided with a fastening hole 121 in its edge for positioning a power supply line. A hollow positioning shaft 13 is extended from the through hole 11 of the first reel cover 12. The hollow positioning shaft 13 is circumferentially provided with a flange 14 adjacent to a wall face of the front end. At least one fastening notch 15 is provided on the flange 14, and at least one positioning column 16 is extended from the front end of the hollow positioning shaft 13.

A second reel cover 2 is provided. A through hole 21 is provided in the center of the second reel cover 2. A plurality of openings 22 are circumferentially provided on the second reel cover. Each opening 22 is provided with a fastening hole 221 in its edge for positioning a power supply line. A grip 3 is connected to the outer surface of the second reel cover 2. An inner ring body 24 and an outer ring body 23 are extended from the through hole 21 of the second reel cover 2. A pivoting notch 25 is provided between the inner ring body 24 and the outer ring body 23. The upper end of the outer ring body 23 is provided with at least one elastic fastener 231 and one positioning hole 232, and the bottom end of the inner ring body 24 is provided with at least one elastic fastener 241. By connecting the positioning column 16 provided on the end edge of the positioning shaft 13 of the first reel cover 1 to the positioning hole 232 provided on the outer ring body 23 of the second reel cover 2, the elastic fastener 232 provided on the outer ring body 23 of the second reel cover 2 will be fastened to the fastening notch 15 provided on the flange 14 of the first reel cover 1. Thus, the first reel cover 1 and the second reel cover 2 are firmly connected to each other without being easily separated.

A rotating ring 4 is provided. A handle 41 is provided in the rotating ring 4. A stopping portion 42 is extended from the rear end edge of the rotating ring 4, and a fastening portion 43 is circumferentially provided on the front end.

By inserting the rotating wheel 4 into the pivoting notch 25 of the second reel cover 2 via the first reel cover 1, the fastening portion 43 provided on the front end of the rotating ring 4 is fastened to the elastic fastener 241 provided on the bottom end of the inner ring body 24 of the second reel cover 2. At this time, the stopping portion 42 on the rear end abuts against the flange 14 of the first reel cover 1, such that the rotating ring 4 cannot pass through the pivoting notch 25 but only can be pivotably connected to the pivoting notch 25 to rotate therein. Thus, the user can hold the handle 41 of the rotating ring 4 to simultaneously twirl the first reel cover 1 and the second reel cover.
